[tdwg-tag] Indicating living versus deceased status in Darwin Core

Hello! Apologies for the newbie question, which I am hoping has reached the correct list.

I'm altering the names of tables in a mark-recapture database to reflect Darwin Core labels as part of a larger open source initiative. I need to indicate in a new field whether a whale shark sighting (occurrence) represents a living or deceased whale shark. Which Darwin Core field would best represent this? A look through the terms in the Quick Reference did not yield an immeidate match for me, but apologies if I missed the obvious. Can you recommend an appropriate field?

Thanks in advance! Jason Holmberg ECOCEAN Whale Shark Photo-identification Library http://www.whaleshark.org
